  Log Message:
  -----------
  Add AArch64 MASK watchpoint support in debugserver

Add suport for MASK style watchpoints on AArch64 in debugserver
on Darwin systems, for watching power-of-2 sized memory ranges.
More work needed in lldb before this can be exposed to the user
(because they will often try watching memory ranges that are not
exactly power-of-2 in size/alignment) but this is the first part
of adding that capability.
